International Classification:

H01M002/12

US Classification:

429/082000, 429/086000

Abstract:

A non-hermetically sealed, electrochemical power source, includes a first electrode, a second electrode, a separator between the first electrode and the second electrode, and a membrane in fluid communication with an environment external to the battery. The second electrode is between the separator and the membrane. The membrane includes a first portion having a different property, e.g., density, porosity, mass transport resistance, thickness, or gas permeability, than a second portion of the membrane. Methods of designing an electrochemical cell cartridge are also disclosed.

Jonathan O'Neill - Bolton CT, US

International Classification:

H01M 8/06
H01M 8/04
H01M 8/24

US Classification:

429414

Abstract:

Fuel cell systems () and related methods involving accumulators () with multiple regions (R, R; R′, R′) of differing water fill rates are provided. At least one accumulator region with a relatively more-rapid fill rate (R; R′) than another accumulator region (R; R′) is drained of water at shutdown under freezing conditions to allow at least that region to be free of water and ice. That region is then available to receive water from and supply water to, a fuel cell () nominally upon start-up. The region having the relatively more-rapid fill rate (R; R′) may typically be of relatively lesser volume, and may be positioned either relatively below or relatively above the other region(s).

International Classification:

H01M 8/10

US Classification:

429480

Abstract:

A fuel cell for a fuel cell power plant having gas diffusion layers which do not have microporous layers, includes a PEM (), a cathode comprising at least a cathode catalyst () and a gas diffusion layer () on one side of the PEM, and an anode comprising at least an anode catalyst () and a gas diffusion layer () on the opposite side of the PEM, and a porous water transport plate having reactant gas flow field channels () () adjacent to each of said support substrates as well as water flow channels () in at least one of said water transport plates. The thermal conductivity of the cathode and/or the anode gas dif- fusion layers is less than about one-quarter of the thermal conductivity of conventional gas diffusion layers, less than about W/m/K, to promote flow of water from the cathodes to the anodes and to the adjacent water transport plates, during start-up at normal ambient temperatures (lower than normal PEM fuel cell operating temperatures).
